Interface states of quantum spin systems

Alain Messager, Bruno Nachtergaele

We review recent results as well as ongoing work and open problems concerning interface states in quantum spin systems at zero and finite temperature.

Rigidity of interfaces in the Falicov-Kimball model

Nilanjana Datta, Alain Messager, Bruno Nachtergaele

We analyze the thermodynamic properties of interfaces in the three-dimensional Falicov Kimball model, which can be viewed as a primitive quantum lattice model of crystalline matter…
